Step-by-Step Guide to Purchasing MAC Addresses from IEEE for Your Devices

發表於 由撰寫發表留言

Currently, the Nordic Wifi module – AN7002Q on Raytac’s AN7002Q-DB-5340 board isn’t loaded with a Wi-Fi MAC address. You can choose to use your own MAC address or request one from Raytac. Below is a complete tutorial for users who would like to purchase MAC addresses themselves.

Note: Raytac provides two free Wi-Fi MAC addresses (2.4GHz & 5GHz bands) for each AN7002Q module.
If you have a Raytac AN7002Q-DB-5340 demo board but have not received the Wi-Fi MAC addresses, please contact us at sales@raytac.com.


★ What is a MAC Address?

A MAC address (Media Access Control address) is a unique identifier used to identify network devices. It is typically composed of six groups of two hexadecimal digits, for example, 00:1A:2B:3C:4D:5E. The first six characters are known as the Organizationally Unique Identifier (OUI), which identifies the manufacturer or supplier of the MAC address. Manufacturers can use the OUI to identify the producer of the device.

Each network device’s MAC address should be unique. It is an important identifier used for unique identification among network devices, ensuring that devices can communicate correctly within a local area network. However, it is important to note that MAC addresses can be modified within a local network, so they should not be relied upon as the sole basis for security.

★ How to Obtain a MAC Address?

The application and distribution of MAC addresses are managed by IEEE (Institute of Electrical and Electronics Engineers). Here’s how to apply for a MAC address from IEEE:
Currently, MAC addresses can only be purchased directly from the IEEE Standards Association in the United States. Depending on the quantity, they can be categorized as:

MA-L (approximately 16 million addresses)
MA-M (approximately 1 million addresses)
MA-S (4096 addresses)


★ Purchase process

1. Register for an IEEE Account
Visit IEEE’s official website to create an account.


2. Log in and go to the MAC Address Purchase Page
After logging in, navigate to the MAC address purchase page: IEEE MAC Address Purchase


3. Select the number of MAC Addresses to purchase.


4. Fill in your purchase information by providing the required details.


5. Confirm confidentiality
Confirm whether the MAC address purchase is confidential. If you are purchasing publicly registered MA-L, select “No" for this option.


6. Choose payment method
IEEE accepts several payment methods, including mailing a U.S. bank draft, wire transfer in U.S. dollars, and online credit card payment.


7. Receive your OUI
Within 7 working days, IEEE will send an email to the registered email address containing the purchased OUI.


After obtaining the OUI, you can retrieve all the purchased MAC addresses using code and then import them into a database or Excel for management.

Secure DFU OTA for nRF52832 solution modules: Creating hex/zip file for implementation – Part 2(Combining/merging built files)

發表於 由撰寫發表留言

Following up – Part 1: Bootloader & Application (Click for article link),

We will be focusing on:

Part 2: Combining & merging built files

in this article.

IC: nRF52832
DK: PCA10040 (for nRF52832)
SDK: 16.0.0
Softdevice: s132_nrf52_7.0.1_softdevice.hex
IDE: Keil C
PC: Win 10


Part 2: Combining & merging built files


Step 1. Execute the combine batch file in bootloader (nrf52832_bootloader_setting_merge.bat) and generate file of nrf52832_bootloader_secure_combin_settings.hex :

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin
set BS= nrf52832_bootloader_secure_settings.hex
set BL= nrf52832_xxaa_s132.hex
set BSBLCombind= nrf52832_bootloader_secure_combin_settings.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %BS% %BL% -o %BSBLCombind%
pause


Step 2. Create a Final.hex file by 3-in-1 batch file(nrf52832_3in1_merge.bat)
※Note : This hex file is created for the production line to pre-load firmware into modules prior to shipment.

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:UsersuserDesktopNordic BLEnRF5_merge toolsnRF52 bin
set SD= s140_nrf52_7.2.0_softdevice.hex
set BLT= nrf52832_bootloader_secure_combin_settings.hex
set APP= nrf52832_xxaa.hex
set SD_BLT=SD_BLT.hex
set Finalfile=Final.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %SD% %BLT% -o %SD_BLT%
pause
mergehex.exe -m %SD_BLT% %APP% -o %Finalfile%
pause


Step 3. Create a DFU(OTA).zip file of nrf52832_xxaa.zip
※Note : This zip file is created for end device DFU(OTA) implementation.

nrfutil pkg generate –hw-version 52 –sd-req 0xCB –application-version 0xFF –application
nrf52832_xxaa.hex –key-file private.pem nrf52832_xxaa.zip

The DFU OTA zip file will be derived.

※Note :
The “0xCB" appeared in the above DOS code(in red font) is the FWID(Firmware ID) for s140_nrf52_7.2.0_softdevice.hex;
FWID can be found from the soft device documents on the Nordic website.



Step 4: Run DFU OTA (On mobile in this example)


4A. Install the nRF Connect APP on mobile, with DFU OTA file: nrf52832_xxaa.zip. (Download link)


4B. Send nrf52832_xxaa.zip via email to mobile device after combination is done on PC, then download it.


4C. Open nRF Connect APP and run connection;


4D. Execute DFU and select “Distribution packet(ZIP)", thus starting the DFU OTA process.


4E. Start DFU OTA → exit the APP after DFU OTA is completed → restart the mobile device.

Secure DFU OTA for nRF52832 solution modules: Guide to create hex/zip file for implementation – Part 1(Bootloader & Application)

發表於 由撰寫發表留言

Here are the guidelines for users to implement Secure DFU OTA(over-the-air) while using nRF52832 Solution modules. (Click on link for Raytac nRF52832 module series)

IC: nRF52832
DK: PCA10040 (for nRF52832)
SDK: 16.0.0
Softdevice: s132_nrf52_7.0.1_softdevice.hex
IDE: Keil C
PC: Win 10

Below are the guidelines to implement Secure DFU OTA by using Raytac’s nRF52832 modules, SDK16.0.0.
It consists of 2 parts:

Part 1: Bootloader & Application


Part 2: Combining and merging built files (Article link)

In this article, we will be focusing on Part 1: Bootloader & Application.

Bootloader


Path: ..\nRF5_SDK_16.0.0_98a08e2\examples\dfu\secure_bootloader\pca10040_s132_ble\arm5_no_packs
Specifically for nRF52832, programmers need to embed ECC(Elliptic Curve Cryptography) into the bootloader.


Step 1. ’micro_ecc_lib_nrf52.lib’ library can be found in the path below, but we need to boot it up first.


Step 2. Unzip ’micro-ecc-master.zip’ to the below path(create a new “micro-ecc” file first).


Step 3. Run ’gcc-arm-none-eabi-7-2018-q2-update-win32.exe’.


Step 4. Make sure the Environment variables in Win10 are set as below. (Follow the steps 1 to 6)


Step 5. Open DOS → run the “make” command under armgcc path → generate’micro_ecc_lib_nrf52.lib’


Step 6. Add ’micro_ecc_lib_nrf52.lib’ into folder: nRF_micro-ecc


Step 7. An error may occur while building bootloader without a public key:
(Shown in red frames in below screenshot)


Step 8. How to generate the public key file in Bootloader?
A. Visit DOS at path: ..\Python27\Scripts
B. Then execute:

nrfutil keys generate private.pem
nrfutil keys display --key pk --format code private.pem --out_file public_key.c


Step 9. Copy the pk[64] code from (public_key.c) into (dfu_public_key.c)
(Shown in red frames in below screenshot)

※Note: Make sure to save the 3 generated files:
private.pem
public_key.c
dfu_public_key.c


Step 10. Generate the bootloader file: nrf52832_xxaa_s132.hex after re-compiling the code files.

Application


Path:
..\nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_uart\pca10040\s132\arm5_no_packs
Before building Application code , some amendments need to be made regarding DFU-related settings and code inside Application:


Step 1. Add code in definition in C/C++ :
BL_SETTINGS_ACCESS_ONLY NRF_DFU_SVCI_ENABLED NRF_DFU_TRANSPORT_BLE=1
(Total 3 steps definitions need to be set up)


Step 2. Add the 3 paths shown below in C/C++ to make DFU work.


Step 3. Add the .c files inside red frame in (Screenshots 1 & 2)
and add the 2 groups of (nRF_DFU & nRF_SVC)(Screenshot 4) under Project(Screenshot 3)


Step 4. Add code into main.c file in Application (..\examples\ble_peripheral\ble_app_uart\main.c)
(Please refer to: main.c file at: ..\examples\ble_peripheral\ ble_app_buttonless_dfu)


Step 5.
The code of file: sdk_config.h (..\examples\ble_peripheral\ble_app_uart\pca10040\s132\config\sdk_config.h)
inside Application needs to be modified.


Step 6. Adjust the IRAM1 value in Target after implementing DFU service:
Make sure the IRAM1 Value of *p_app_ram_start is modified from default: 0x20002AD8 0xD528 to
0x20002AE8 0xD518, as shown in the red frame in the bottom right corner.
In this case, the program should run/advertise successfully.


Step 7. Create a file of: nrf52832_xxaa.hex after building application code files.



Step 8. Create a bootloader setting file of nrf52832_bootloader_secure_settings.hex via DOS.
nrfutil settings generate –family NRF52 –application nrf52832_xxaa.hex –application-version 3 —
bootloader-version 2 –bl-settings-version 1 nrf52832_bootloader_secure_settings.hex –no-backup

※Stay tuned for Part 2: Combining and merging built files in the next article, scheduled release in next week(04-Sep-2024).

FAQ: How to write MAC address into the OTP memory of Raytac’s nRF7002 Wi-Fi module/AN7002Q-DB-5340 DevKit

發表於 由撰寫發表留言

Recently we have received the FAQ: how to write MAC address into the OTP memory of Raytac’s AN7002Q-P Nordic Wi-Fi module? In this article, we’ll get this question explained to give customers a more smooth experience using the AN7002Q-nRF5340 Demo Board(AN7002Q-DB-5340).

Is there an existing Wi-Fi MAC address in the AN7002Q part on the DevKit?

Currently, the AN7002Q module on Raytac’s AN7002Q-DB-5340 board has no Wi-Fi MAC address.


When running Wi-Fi Scan code/Station code/Shell code…etc. on NCS v2.6.0 (and later versions), the AN7002Q module must have a programed Wi-Fi MAC address to function properly.

Therefore, it’s necessary to follow the below process:
1. Program the original Wi-Fi radio test code (..\nrf\samples\wifi\radio_test) into the MDBT53 section,
2. Then write the Wi-Fi MAC address in to the AN7002Q section(nRF7002 IC) via command.

After this, program the original Wi-Fi Scan code/Station code /Shell code … into the 5340, and it will function properly.

**Raytac will assign 2 Wi-Fi MAC addresses(for both 2.4GHz & 5GHz) to every AN7002Q module.
*If customers don’t have Wi-Fi MAC addresses for DevKit development yet, please reach out to service@raytac.com



==================================================================================

Case study 1. SCAN code example

Scenario:
Following error occurred when building the SCAN example code, flash it onto the AN7002Q-DB-5340 board, and run the test.

Solution:

When running Wi-Fi scan code on NCS v.2.6.0 or later version, the OTP memory in the AN7002Q module must have a Wi-Fi MAC address programmed in for the Wi-Fi scan functionality to work properly.

(Note: OTP is a One-Time programmable memory, which means the value can only be written once.
The customer must aware of this before performing the OTP operation.)

1. Program the original Wi-Fi radio test code (..\nrf\samples\wifi\radio_test) into the MDBT53 section,
then manually input and execute the following OTP read command.

wifi_radio_ficr_prog otp_read_params

If you see both MAC0 and MAC1 display a value of 0xFF, as shown in above, it means that you haven’t written the Wi-Fi MAC address into the AN7002Q’s OTP.

2. Manually issue the OTP write command to write the Wi-Fi MAC address into the OTP.

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/radio_test/ficr.html

wifi_radio_ficr_prog otp_write_params 0x120 0xDDCCBBAA 0xFFEE

wifi_radio_ficr_prog otp_write_params 0x128 0xDDCCBBAA 0xFFEE


After you complete the above, use the OTP read command in below to check if the Wi-Fi MAC address value was written.
The MAC0 and MAC1 should display the value you’ve input from the OTP write command.

wifi_radio_ficr_prog otp_read_params

3. Program the original Wi-Fi SCAN code back into the MDBT53, the Wi-Fi scan functionality should work properly.

==================================================================================

Case study 2. Shell code example

SDK Wi-Fi example test – Running Shell Code on AN7002Q-DB-5340:
Scenario:
An error occurs while running Shell code on AN7002Q-DB-5340.

Solution:
The AN7002Q-DB-5340 is paired with nRF5340 DK for development,
but neither of the 2 boards has an external MX25R64 (Serial NOR Flash) component.
So far, only the nRF7002DK board is equipped with the MX25R64.

Therefore, while running the original Wi-Fi shell code, the program will enable SPI NOR.

When using AN7002Q-DB-5340, you should add CONFIG_SPI_NOR=n in the prj.conf file to disable SPI NOR, to turn off any configurations related to it.

After recompiling and flashing, the shell code function
( e.g., Wi-Fi scan/Wi-Fi connect/net ping ..) should work properly.

After the installations are completed, you can see the following applications under the:

“Programs and Features" section in the Control Panel.

3. Programming/Development

nRF Connect SDK (NCS) supports development using the free VS (Visual Studio) Code IDE.
Here’s how to select and install the NCS SDK version (nRF Connect SDK vx.x.x):


Step1.

Open “nRF Connect for Desktop” → Choose “Toolchain Manager” → then click” Open”


Step2.

You’ll see a list of nRF Connect SDK versions. It’s recommended to install NCS v2.6.0 or later.
Here, we use NCS v2.6.0 as an example.


Step3.

Before installing NCS v2.6.0, confirm the installation path (Default path → C:\ncs).


If you want to change the path, click “Select directory”, and press OK.


Step4.

After installing the nRFConnect SDK v2.6.0, click “Open VS Code”.


Step5.

Open the Wi-Fi scan example


Step6.

Add build configuration → select the board and compile.


Select board: nrf7002dk_nrf5340_cpuapp.


Step7.

After compilation, a hex file will be generated.


Step8.

Under ACTIONS, you can choose to Build, Debug, or Flash.


Build:


Debug:


Flash:

4. Programming

nRF Connect SDK(NCS) supports programming. You can use the “Programmer” tool to flash .hex file.
Here’s how:


Step1.

Open “nRF Connect for Desktop” → Select “Programmer” → then click” Open”.


Click “Select Device”;


Since AN7002 Wi-Fi IC does not act as an MCU,
we can only flash the .hex file into the MDBT53(nRF5340) BLE IC.


Click “Add file” to add the .hex file.


Step2.

Select the .hex file you want to flash.


The hex file will be written into the part of the memory layout (where orange part is highlighted).


Slashes will be displayed in the circled part during the flash process.


Step3.

Once the flash process is completed, connect Raytac’s AN7002Q-DB-5340 development board to PuTTY.

Tx to p0.20

Rx to p0.22

GND to GND

This is a closer look into the pins that will be connected.


The flash process is completed when the LOG is displayed as circled below.


Check if hardware connection is successful using PuTTY.

Secure DFU OTA for nRF52840 solution modules: Guide to create hex/zip file for implementation – #3(Combining/merging built files)

發表於 由撰寫2 則迴響

Following up – Part A: Bootloader (Click for article link) and Part B: Application (Click for article link)

We will be focusing on:

Part C: Combining & merging built files

in this article.

IC: nRF52840
DK: PCA10056 (for nRF52840)
SDK: 17.1.0
Softdevice: s140_nrf52_7.2.0_softdevice.hex
IDE: Keil C
PC: Win 10

Part C: Combining & merging built files

Step 1. Execute the combine batch file in bootloader (nrf52840_bootloader_setting_merge.bat) and generate file of nrf52840_bootloader_secure_combin_settings.hex :

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin
set BS= nrf52840_bootloader_secure_settings.hex
set BL= nrf52840_xxaa_s140.hex
set BSBLCombind= nrf52840_bootloader_secure_combin_settings.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %BS% %BL% -o %BSBLCombind%
pause

Step 2. Create a Final.hex file by 3-in-1 batch file(nrf52840_3in1_merge.bat)
※Note : This hex file is created for the production line to pre-load firmware into modules prior to shipment.

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Users\user\Desktop\Nordic BLE\nRF5_merge tools\nRF52 bin
set SD= s140_nrf52_7.2.0_softdevice.hex
set BLT= nrf52840_bootloader_secure_combin_settings.hex
set APP= nrf52840_xxaa.hex
set SD_BLT=SD_BLT.hex
set Finalfile=Final.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %SD% %BLT% -o %SD_BLT%
pause
mergehex.exe -m %SD_BLT% %APP% -o %Finalfile%
pause

Step 3. Create a DFU(OTA).zip file of nrf52840_xxaa.zip
※Note : This zip file is created for end device DFU(OTA) implementation.

nrfutil pkg generate –hw-version 52 –sd-req 0x100 –application-version 0xFF –application
nrf52840_xxaa.hex –key-file private.pem nrf52840_xxaa.zip

The DFU OTA zip file will be derived.

※Note :
The “0x100" appeared in the above DOS code(in red font) is the FWID(Firmware ID) for s140_nrf52_7.2.0_softdevice.hex;
FWID can be found from the soft device documents on the Nordic website.


Step 4: Run DFU OTA (On mobile in this example)


4A. Install the nRF Connect APP on mobile, with DFU OTA file: nrf52840_xxaa.zip. (Download link)


4B. Send nrf52840_xxaa.zip via email to mobile device after combination is done on PC, then download it.


4C. Open nRF Connect APP and run connection;


4D. Execute DFU and select “Distribution packet(ZIP)", thus starting the DFU OTA process.


4E. Start DFU OTA → exit the APP after DFU OTA is completed → restart the mobile device.

Secure DFU OTA for nRF52840 solution modules: Guide to create hex/zip file for implementation – #2(Application)

發表於 由撰寫2 則迴響

Following up-Part A: Bootloader (Click for article link)

We will be focusing on:

Part B: Application

in this article.

IC: nRF52840
DK: PCA10056 (for nRF52840)
SDK: 17.1.0
Softdevice: s140_nrf52_7.2.0_softdevice.hex
IDE: Keil C
PC: Win 10


Part B: Application

Path: nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_uart\pca10056\s140\arm5_no_packs

Before building Application code , some amendments need to be made regarding DFU-related settings and code inside Application:

Step 1.


1A. Add code in definition in C/C++ :
BL_SETTINGS_ACCESS_ONLY NRF_DFU_SVCI_ENABLED NRF_DFU_TRANSPORT_BLE=1
(Total 3 steps definitions need to be set up)


1B. Add “include path” in C/C++


1C. Add the .c files inside red frame in (Screenshots 1 & 2)
and the 2 groups of (nRF_DFU & nRF_SVC)(Screenshot 3) under Project(Screenshot 4)



1D. Add code into main.c file in Application (..\examples\ble_peripheral\ble_app_uart\main.c)
(Please refer to: main.c file at: ..\examples\ble_peripheral\ ble_app_buttonless_dfu)


1E. The code of file: sdk_config.h (..\examples\ble_peripheral\ble_app_uart\pca10056\s140\config\
sdk_config.h) inside Application needs to be modified.


1F. Adjust the IRAM1 value in Target after implementing DFU service:
Check on the IRAM1 Value of *p_app_ram_start to be modified from default: 0x20002AE8 0x3D518 to 0x20002AF8 0x3D508, as shown in the red frame in the bottom right corner.
In this case, the program should run successfully.


1G: Create a file of: nrf52840_xxaa.hex after building application code files.


Step 2. Create a bootloader setting file of nrf52840_bootloader_secure_settings.hex : (via DOS)

nrfutil settings generate –family NRF52840 –application nrf52840_xxaa.hex –application-version 3 — bootloader-version 2 –bl-settings-version 1 nrf52840_bootloader_secure_settings.hex –no-backup


※Stay tuned for #3 – Part C: Combining and merging built files in the next article,

scheduled release in next week(05/06/2024).
